#includeIn this example, `mouseEventHandler` is a function that takes a `MouseEvent` object as its parameter. When the left mouse button is clicked, the function prints out the location of the click using the `getX` and `getY` methods. The `setmouseclickcallback` function sets this function as the event handler for mouse clicks. The package library for MouseEvent in C++ depends on the graphics library used. In this example, the code uses the graphics.h library, which is part of the Borland Turbo C++ IDE. Other libraries that include MouseEvent functionality are likely to have different package libraries.#include using namespace std; void mouseEventHandler(MouseEvent e) { if (e.getButton() == MouseEvent::LEFT_BUTTON) { cout << "Left button clicked at (" << e.getX() << ", " << e.getY() << ")" << endl; } } int main() { initwindow(500, 500); // create a window for graphics setmouseclickcallback(mouseEventHandler); // set the mouse event handler while (!kbhit()) { // loop until a key is pressed // draw graphics here } closegraph(); // close the graphics window return 0; }
